Research On Classroom Energy Saving Lighting System Based On Machine Vision

With the rapid development of the national economy and the continuous progress of the society,higher education has been paid more and more attention,especially from the 99 year,after the expansion of the university enrollment,the number of colleges and universities has doubled,first of all,the number of classsroom in colleges and universities has increased dramatically.Due to the use of open management mode in college classrooms,no fixed groups of students,coupled with the full energy-saving awareness is not high,classroom ever burning lamps,unmanned also turn on the lights and fewer lamps open phenomenon everywhere,is not only a waste of energy also increased the cost of running the school.Under the premise of meeting the needs of teachers and students in normal learning and living,to solve the problem of intelligent classroom lighting has become a very concerned problem.In recent years,the State advocates the low carbon life of the green environmental protection,the university promotes the construction of "Saving Campus",and the waste of classroom lighting is an urgent need to solve the problem.Although the related research of the University's lighting energy saving has achieved great results,there are still a lot of unnecessary energy consumption problems in daily operation.In order to solve the problem of energy consumption in university classroom lighting,this paper presents a systematic analysis on the basis of the classroom lighting energy saving technology,which is used to solve the problems,and puts forward the control scheme and key technology of classroom energy saving based on machine vision.Through the video surveillance system,the classroom image is collected in real time and the results of the classroom enery region,which existing persons,are obtained by computer image processing.The results are transmitted to the electrical control module based on PLC.Finally,the control of the classroom lighting is realized.The main research content of this paper is as follows:(1)The control scheme and key technology of classroom energy saving lighting based on machine vision are presented.(2)Through the video surveillance system,the image of the classroom is collected in real time and the image processing results are transmitted to PLC by serial communication,Control of classroom lighting equipment in the classroom.(3)The different method of image processing in the classroom is studied.The template frame difference method is proposed to verify the image processing method effect.(4)Through the simulation of the simulation model system,it is proved that the energy saving lighting system based on machine vision is feasible.
